ABSTRACT In an apparatus for manufacturing a hollow body, said hollow body comprised of an injection-molded head piece a body part formed by blowing, e.g., blow molding, a preform segment which segment is integral with the head piece, wherewith the said apparatus comprises a ring-shaped nozzle wherein a ring-shaped nozzle opening is defined between a nozzle cone piece and a nozzle opening piece , said apparatus further comprising a withdrawal device operative with respect to the ring-shaped nozzle , which withdrawal device is axially reciprocally movable and has a recess , it is desired to enable production of different and/or novel configurations of the body parts or the hollow body. This is achieved by means of an additional mold device which is provided for an additional forming operation operative on the preform segment adjoining the head piece , which operation relates to the walls of the body part , wherewith said additional mold device provides an offset in the radial sense with respect to the ring-shaped nozzle opening. By providing a specific radial offset between the nozzle opening and other parts of the apparatus, one can produce special configurations of the preform segment prior to the blowing operation.
